ABSTRACT In this article, we study the $\frac{1}
{2}^ -$\frac{1}
{2}^ - and $\frac{3}
{2}^ -$\frac{3}
{2}^ - heavy and doubly heavy baryon states $\Sigma _Q \left( {\frac{1}
{2}^ - } \right)$\Sigma _Q \left( {\frac{1}
{2}^ - } \right), $\Xi '_Q \left( {\frac{1}
{2}^ - } \right)$\Xi '_Q \left( {\frac{1}
{2}^ - } \right), $\Omega _Q \left( {\frac{1}
{2}^ - } \right)$\Omega _Q \left( {\frac{1}
{2}^ - } \right), $\Xi _{QQ} \left( {\frac{1}
{2}^ - } \right)$\Xi _{QQ} \left( {\frac{1}
{2}^ - } \right), $\Omega _{QQ} \left( {\frac{1}
{2}^ - } \right)$\Omega _{QQ} \left( {\frac{1}
{2}^ - } \right), $\Sigma _Q^* \left( {\frac{3}
{2}^ - } \right)$\Sigma _Q^* \left( {\frac{3}
{2}^ - } \right), $\Xi _Q^* \left( {\frac{3}
{2}^ - } \right)$\Xi _Q^* \left( {\frac{3}
{2}^ - } \right), $\Omega _Q^* \left( {\frac{3}
{2}^ - } \right)$\Omega _Q^* \left( {\frac{3}
{2}^ - } \right), $\Xi _{QQ}^* \left( {\frac{3}
{2}^ - } \right)$\Xi _{QQ}^* \left( {\frac{3}
{2}^ - } \right) and $\Omega _{QQ}^* \left( {\frac{3}
{2}^ - } \right)$\Omega _{QQ}^* \left( {\frac{3}
{2}^ - } \right) by subtracting the contributions from the corresponding $\frac{1}
{2}^ +$\frac{1}
{2}^ + and $\frac{3}
{2}^ +$\frac{3}
{2}^ + heavy and doubly heavy baryon states with the QCD sum rules in a systematic way, and make reasonable predictions for their
masses.
